Ive been using my X for over a month now with the sd card they provided. Today I launched angry birds and the phone rebooted randomly. When it came back on, everything on my memory card is gone and there is an icon up in the dock saying my memory card is empty. If I try to format it nothing happens and the icon wont go away. I know I lost everything, but why did this happen and how do I fix it and make my memory card work? I appreciate any help. thanks!
